                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Fog during the afternoon which lifted before sunset, but the humidity
 remained high and lots of clouds.  Dewpoint sensor (temperature) was not
 working so I had to rely on SDSS humidity (as if I didn't know it was
 humid outside)
 The clouds broke a little about an hour before the start of twilight,
 unfortunately it was so wet it kept the humidity above closure limits.
 I did some housekeeping tasks tonight to pass the time.
 We gave up around 04:45.
